One of the common questions I get to hear from people considering the hourglass hip procedure is, “How much fat can you inject in the hips?” There are a number of factors that are taken into account when it comes to the volume of the fat that can be injected in the hips. First off, it depends on how much excess fat is available in your body areas like the abdomen, sides, flanks, and upper back. Secondly, your aesthetic goals are taken into account. Since the procedure is undertaken to achieve the hourglass body, the plastic surgeon also needs to be fully aware of the features and minute details of the hourglass body. If your hips are too narrow, you may need more fat injections than someone who already has moderately wider hips. Your body mass index would also be taken into account when determining the amount of fat needed to deliver you the hourglass body. If your BMI is high, you would need a greater volume of fat to achieve visible outcomes. On the other hand, if your BMI is low, you may not require more fat. Even low volume fat transfer can deliver you noticeable results in this case. There is also a limit to the amount of fat that can be removed from the body during a single session. When this limit is crossed, you may experience health complications. For example, fat necrosis of the hips fat. This can happen even without reaching the maximum amount. Typically, majority patients require 300 – 400 cc of fat injection in each hip in order to achieve the hourglass body. This amount can differ from patient to patient depending on the existing hip structure, size, and shape, besides the availability of excess fat in the body. If the surgeon thinks you need more fat to achieve the hourglass body and there is an excess amount of fat available in your body areas, you may be advised to undergo multiple sessions of the hip procedure to achieve the desired aesthetic outcomes. The fat extraction, fat processing, and fat grafting also need to be done properly and carefully in order to make your hips wider. This is particularly very important when the excess fat in your body is limited.
